The Toronto Maple Leafs, for the second time in a month, saw one of their top AHL prospects take a shot to the head, stay on the bench, return to the game, then eventually leave with a headache.

This time, it was Toronto Marlies forward Nazem Kadri, who took a high elbow from Hamilton Bulldogs "winger" Zack Stortini (104 penalty minutes, one assist on the season) with about 5 minutes left in the second period. Stortini was ejected, and Kadri skated during the ensuing power play.

By the third period, Kadri, a 22-year-old former first-round pick with 25 points in 25 games this season, wasn't playing because of headaches.

As noted by Cam Charron at The Leafs Nation, it's a replay of what happened with defenseman Jake Gardiner on Dec. 8. Gardiner, who had 30 points last season for the Leafs despite being just 21 years old, hasn't played since, with reported concussion-like symptoms.
